Abstract: A lighting device for passenger conveyors, such as escalators and travelators, is provided particularly in the region of the handrail and/or skirting of the passenger conveyor, and includes at least one light-guide oriented in the conveying direction of the passenger conveyor, substantially continuously, having lateral light emission and which in the region of at least one of its ends can receive the bundled light beam of a light source. The light-source runs along the length of the conveyor and its end faces a projector whereby light generated by an electric lamp of the projector is passed through a light concentrator to bundle the light into a concentrated beam. The bundled light beam is projected onto the end of the light-guide thereby lighting one of the handrail and the step track, respectively, along the transport direction of the passenger conveyor.
